Due to events in Tulsa the last 6 months, I have been transitioning my EDC from a S&W 640-1 to a Sig P365XL. My Sig didn't have a safety, so I've been carrying it in condition 3. I re-evaluated that situation, and decided to install a safety. I'm comfortable with my .45's and other 9mm's with a safety, but all of them are full size and not good for CC. Originally planned to do it myself, but decided that I shouldn't attempt something that can obviously adversely affect the Sig operation. I had seen recommendations for David (SPDguns) and contacted him. The work was done timely, it is a very good job, and the cost was very reasonable. I haven't had a chance to take it out to the range yet (Snake Creek is closed right now for the Sporting Clay Championship), but I have been dry-firing quite a bit this afternoon, and haven't encountered any issues. I highly recommend SPDguns!!
